Fruit is a big part of the solution, but if you only stick to that you're going to be left craving fats and protein (and if your stomach is sensitive, feeling sick from all that acidic and sugary fruit). Identify healthy fats and sources of protein. My list includes olive oil, whole-grain bread, low-fat cheese, hummus, avocados. This list may not be the pinnacle of health (I don't know), but it goes a long way towards nutrition and heading off cravings for junk.
